j 13s it k wn t a 'l, DQRE W- ot-L, eitlzen of the United States'of America, residing at Cleveland,- in the ,county of Guyahoga' and State of Ohio, have invented certain new i and useful Improvements in Pipe- Co, plers and I hereby declare the followlng t0 .6 a full, clear, and exact description of the inyention, such as enable others skilled 1n the art to which it pertains to make This invention relates to pipe cou lers or sleeves adapted to couple together t e ends of pipe sectlons ,or to repair leaking or weak part of pipe. I

The primary object of my invention is the provision. of a coupler or pipe clamping sleeve and Ml consistingof two component parts, substantlally seml-cyhndrical inshape which when shifted longitudinally of each other to clamping position will grip the pipe more firmly, en once inposition are less liable to become loose, than the couplers or sleeves heretofore employed.

A further object is the provision of a coup ler or clamping sleeve having the above-chanacteristics and which can be easily and chea ly manufactured.

. 1th these ends in view my invention'consists of a coupleror sleeve ha'vin certain novel features of construction whic are described in the following detailed description, set forth in the appended claims and shown in the accompanying drawings. g

In the drawings Flgure 1 is an elevation of my improved coupleror pipe clamping sleeve attached to a pipe. 2 is an e evation of the two parts of the sleeve-shown apart or separated. Fig. 3 is an end view ,of the" sleeve looking at the left'end of Fig.1. Fig. 4 is an end view of the sleeve looking at the right end of Fig. -1.

Referring now to thefigures of the drawing, 10 represents a pi e or the adjacent ends of two pi e sections a out which is clamped the coup er or sleeve constructed in accordance with my invention. This clamping sleeve consists in two parts 1 and 2 which are substantially semicylindrical in shape and are adapted to be placed in clamping position about a pipe or the adjacent ends 0 two pipes or sections by shifting the same longitudinally of each other.

The portion 1 of the sleeve is provided along one. edge or face with an outwardly extendin'gflange 3 extending the length of the sleeve portion 1.

opposite side.

respect to the axis of the sleeve or the same, the face ofthe flange being continuous with or flush with the edge of the sleeve portion 1, and on the opposite side is provided with an outwardly rounded portion or flange 4 which curves inwardly forming a slot 5 which likewise extends the length of the portion 2 of the sleeve is provided along one face with an outwardly extending flange -6 and along the, opposite face with an out- Ward'ly rounded portion or flange 7 which curves inwardly forming a slot 8. When the two parts of the sleeve are in clamping position thefl'ange of each part en ages the slot of the other part so as to be 100 ed together. The adjacent or abutting faces of the two parts of the sleeve on one side are not parallel with the faces on the opposite side, but on one side, for a purpose to a pear, the faces are inclined with respect to the faces on the to the several be seen that on By referring figures' of the drawing it wil one side of the sleeve, the adjacent flat faces and the corresponding flange and groove on the two parts res. ectively are inclined with pipe and on the-opposite side the adjacent at facesandthe corresponding flange and groove on thetwo parts res ectively are parallel with the axis of the s eeve or pipe This construction forms one 'of the. main features of my ifivention, for, as will'be explained, it causes the sleeve to grip the pipe more firmly than 'with the usual constructions and to lessen the liability of accidental displacement or relative movement of the two parts.

By referring particularly to Fi s. 1 and 2 it will be seen that the edge or face of the portion 1 and the outwardly extending flange 3 are tapered or inclined while on the opposite side of the same portion the groove 5 is parallel to the axis. Also as appearsfrom these figures the groove 8 of the portion 2' which receives the flange 3 of the portion 1 is similarlytapered or lnclined, and on the opposite side the flan e 6 which is received in the groove 5 is para el to the'axis. As appears rom Figs. 1 and 2 the adjacent ta- He'red faces or edges and the corresponding ange and groove extend both'above and below the axis of the sleeve or pipe; at the right hand end, as s i own in Fig. 1, being below the axis and at ,the left hand end being above the axis.

When it is desired to clamp the parts of the In a similar manner sleeve about a pipe or the ends'of two pipe sections, one part of the sleeve is placed on one side of the pipe, and the otherpart of the sleeve on the opposite side of the pipe, with the flange and groove on one part registering with the groove and flange respectivel on the other part. The parts or halves ot the sleeve can then be moved longitudinally of the pipe and toward each other, with the flan e of each part sliding within the groove of t e other part. The peculiar arrange ment of the flanges and grooves causes the arts to interlock very securely thereby orming a permanent union between the pipe and the said sleeve or coupler sections.

I do not desire to be confined to the exact details shown but aim in my claims to cover all modifications which do not involve a departure from the spirit and scope of my invention.

What I claim is,-'

1. A pipe coupler or clamping sleeve, consisting of two parts having longitudinally ex tending abutting faces, said parts having on opposite sides interlocking flanges and grooves, the adjacent" faces on one side being inclined to the axis of the-sleeve and on the olpposite side being parallel to the axis of the s eeve.

2. A pipe coupler or clamping sleeve consisting of two parts substantially semicylin' drical in shape, said parts having on opposite sides interlocking flanges and grooves, the correspondin flange and groove on one side being inclined sleeve, and the flange and groove on the opposite side being parallel with the axis of the sleeve. 7

3.. A pipe coupler or clamping sleeve consisting of two parts having longitudinally extending abutting faces, each part having along one face an outwardly extending flange, and along the opposite face a groove, the flange of each part engaging. the groove of the other. part, whereby said, parts are locked together, the corres )onding flange and groove on one side of the sleeve being inclined with respect to the axis of the sleeve and the correspondin flange and groove on the opposite side of the sleeve being parallel to the axis of the sleeve.

In testimony whereof, I sign the foregoing specification, in the presence of two witnesses.
